We have written a lot about Pennsylvania's Voter ID Law, which has been put on hold by the courts for the upcoming election. Turns out we're not alone when it comes to voting suppression.

That may not be news to you, but you may be surprised to know that more than 180 voter suppression laws were proposed in 2011 and 2012, according to The New York Times. These are laws defined as restricting or limiting voter access based on a myriad of qualifications.

Among the voter suppression laws enacted over the past two years: reductions to early voting, tougher voting rules for ex-convicts, limitations to voter registration drives, and (drum roll, please) voter identification requirements. The data were collected and analyzed by New York University's Brennan Center for Justice.

From the Times report:

A wave of at least 180 proposed laws tightening voting rules washed over 41 statehouses in 2011 and 2012, by the count of New York University's Brennan Center for Justice. Only a fraction of those bills passed and survived the scrutiny of the courts, but the new rules cover voters in 13 states, several quite populous, in time for next month's election. More laws are to start afterward.

Partisans and experts are arguing, over the airwaves and in the courts, about the effects of all this on voter turnout, for which few studies exist. (The most rigid voter ID laws are believed to affect about 10 percent of eligible voters, said Lawrence Norden of the Brennan Center.)
